Question

Process

Question

Corrective

Action

Yes

The fan is faulty

and must be

replaced.

Correct

wiring.

Repair.

Yes

Replace the appropriate switch after verifying the following:

•

Baffles are in the radiant tube(s) farthest from the burner.

•

The heater, fan blower, squirrel cage, intake and exhaust are free from

dirt and obstructions.

•

The 4” air intake pipe does not exceed 20 feet and/or 2 elbows.

•

There is not a negative pressure experienced at the area of air intake

(i.e., attic space, high winds, very tight building).

If any of the above are occuring, please address the problem.

Is resistance through

the ignitor 50-400

Ω

Replace

ignitor.

Consult

factory.

Yes

The heater is equipped with two safety pressure switches. The

burner switch, located in the fan compartment, is a normally

open pressure switch. The exhaust switch, located in the

valve compartment, is a normally closed pressure switch.

Temporarily

place jumpers across the terminals of the switch,

one at a time (be sure to reinstall the control box cover).

Does the light energize?

Replace faulty light.

Temporarily place jumpers

across the thermal fuse

(reinstall control box cover).

Does the light energize?

Replace

thermal fuse.
